The total area of Sheridan County is 2,470 square miles. The Niobrara River flows east-west through the center of the county. Sheridan County is comprised primarily of Sandhills and Plains, with smaller areas of Valleys, Bluffs and Escarpments, and Dissected Plains topographic regions1, with the majority of land used as rangeland for livestock. Climate For Sheridan County, the normal high temperature for the month of July is 86.1°F and the normal low temperature for the month of January is 11.7°F. On average, Sheridan County receives 18.59 inches of precipitation and 36.1 inches of snowfall per year. The table below compares climate indicators with those of the entire state. Climate data is helpful in determining if certain events are higher or lower than normal. For example, if the high temperatures in the month of July are running well into the 90s, high heat events may be more likely which could impact vulnerable populations.

Transportation Sheridan County’s major transportation corridors include Nebraska Highway 2 running east-west, Nebraska Highway 27 running north-south, Nebraska Highway 250 running north-south, Nebraska Highway 87 running north-south, and U.S. Highway 20 running east-west. US Highway 20 is the major corridor of transport through the county. A Burlington Northern Santa Fe rail line also bisects the southern edge of the county. Rail lines commonly transport hazardous materials through the county including coal, oil, or waste materials. The county also has air landing strips located in Hay Springs, Rushville, and Gordon. Critical facilities along these major transportation routes include the County Courthouse, hospital, police departments, County Sheriff’s office, and fire departments in Rushville, Hay Springs, and Gordon. This information is important to hazard mitigation plans insofar as is suggests possible evacuation corridors in the county, as well as areas more at risk to transportation incidents. Chemical Transportation Hazardous materials are commonly transported by a range of transportation methods, including highways, rail, air, and pipeline. Railway and highway transportation spills are the most frequently occurring chemical transportation incidents. While incident proximity will always occur near or on transportation methods, it is not possible to predict precise locations of possible future events. Proximity of pipelines, rail lines, and highways near critical facilities or vulnerable population centers, including schools, daycares, nursing homes, and/or hospitals, increases overall vulnerability to chemical transportation spills. A BNSF rail line, State Highways 2, 27, and 250, and U.S. Highway 20 are all commonly used to transport hazardous chemicals across the County. 1 Center for Applied Rural Innovation. “Topographic Regions Map of Nebraska.” 2001. http://digitalcommons.unl.edu/caripubs/62. 2 National Centers for Environmental Information. “1981-2010 U.S. Climate Normals.” Accessed December 2019. https://www.ncdc.noaa.gov/cdo-web/datatools. 3 High Plains Regional Climate Center. “Monthly Climate Normals 1981-2010 – Hay Springs NE.” Accessed December 2019. http://climod.unl.edu/. 4 REGION 23 EMA HAZARD MITIGATION PLAN | 2020 SECTION SEVEN: SHERIDAN COUNTY COMMUNITY PROFILE In the county, a spray plane crashed and contaminated a small area. Local response resources include hazmat crews in Chadron and Scottsbluff. The local planning team indicated vulnerable populations are located at the Parkview Lodge in Rushville near major routes. Private entities, local emergency response units, and state resources have strict regulatory oversight and emergency action plans in place to respond to significant chemical spills. Demographics The following figure displays the historical population trend from 1890 to 2017. This figure indicates that the population of Sheridan County has been declining since the 1930s. This is notable for hazard mitigation because communities with declining population may also have a higher level of unoccupied housing not being maintained. Furthermore, areas with declining population will be less prone to pursuing residential/commercial development in their areas, which may reduce the number of structures vulnerable to hazards in the future. Decreasing populations can also represent decreasing tax revenue for the county which could make implementation of mitigation actions more fiscally challenging.

This is relevant to hazard mitigation insofar as the very young and elderly populations may be at greater risk from certain hazards than others.

Median home value and rent are also both lower than the rest of the state. These economic indicators are relevant to hazard mitigation because they indicate the relative economic strength compared to the state as a whole. Areas with economic indicators which are relatively low may influence a county’s level of resilience during hazardous events.

According to 2017 ACS 5-year estimates, the county has 2,916 housing units with 79.1% percent of those units occupied. Approximately 20% of homes in the county are vacant. Vacant homes are more likely to become dilapidated with unsafe conditions, increasing risk to fire and lowering overall property home values and tax base. There are approximately 237 mobile homes in the county. Housing age can serve as an indicator of risk as structures built prior to state building codes may be at greater risk. Finally, residents that live in mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe winter storms.
